HOT-WATER BOTTLE.

SPECIFICATION forming part of Letters Patent N o. 684,447, dated October 15, 1901.

Application filed May 10,1901. Serial No. 591690. (No model.)

To @ZZ whom t may concern:

Be it known that I, HARVEY F. MITZEL, a citizen of the United States, residing at Barberton, in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Hot-Water Bottles, of which the following is a specification.

j My invention has relation to improvements in that class of appliances of soft rubber known as water bags or bottles for holding cold or hot water to be applied to the person to relieve pain and like purposes or to be used as a source of supply for fountainsyringes. Heretofore such bags have been made of two sheets of rubber prepared for vulcanization, cut into two pieces to form the sides and the edges joined and cemented. Much objection has been found to these bags because of the tendency of the seam or joint to leak, experience having demonstrated that this is the weak point.

The object of my invention is to overcome this objection and to produce a bag of peculiar smoothness and exibility and of equal strength at all points.

To the accomplishment of the aforesaid object my invention consists in the peculiar and novel construction hereinafter described and then specically pointed out in the claim, reference being had to the accompanying drawings, forming a part of this specification.

In the accompanying drawings, in which similar reference-nu merals indicate like parts in the different views, Figure l is a view of a complete water-bag embodying my invention; Fig. 2, a View of the metal nipple; Fig. 3, a view of the funnel-top; Fig. 4, a view of the top of the bag with the metal nipple and funnel-top united, showing the method of uniting them, the last three figures being on a larger scale than Fig. l; Fig. 5, a vertical central section of a completed hot-water bottle embodying my invention.

Referring to these figures, 1 is a flat bag having a converging top to form a neck and made upon a mold of proper Asize and shape by repeatedly dipping the mold in a siccative solution of pure rubber dissolved in naphtha, by which successive thin layers of rubber are 5 o deposited on the mold ,and allowing each layer to dry before applying the next. When the bag has acquired the required thickness, it is immersed in a curing-bath to harden the rubber. This bath is composed of chlorid of sulfur and bisulid of carbon. There is thus prepared a bag With a short neck, through which neckthe mold is Withdrawn, the elasticity of the rubber permitting this operation. A funnel-shaped top 3 of rubber prepared in the same manner as the bag is now provided. Into the lower end of this funnel-shaped top 3 is inserted a metallic nipple 2, consisting of a short tube having end iianges 6 and 7 and internally either screw-threaded or smoothed, as desired. The lower iiange 7 is not covered by the rubber funnel-top 3, but is allowed to project, the rubber coming up against its inner face. Now the funnel inclosing the nipple is inserted into the neck of the bag or bottle to such a depth that the neck will inclose the lower ange '7 and substantially all of the intermediate space between the flanges, and of course inclosing the rubber funnel where it itself incloses the nipple. A wire et is then wrapped about the neck of the bottle, thereby clamping it to the funnel-top, a band of rubber 5 is then placed about the wire and neck, thus making a finish for the joint between the parts.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

An improved hot-water bottle consisting of a bag, a neck integral therewith, a funneltop, a flanged nipple to be inserted in the funnel-top, said funnel-top and nipple arranged to be inserted in the neck of said bottle, said neck arranged to overlap and inclose the portion of said funnel-top inclosing said nipple, a binding-wire to fasten said neck about said funnel-top and a rubber band to cover said union, substantially as shown and described.

In testimony that I claim the above I hercunto set my hand in the presence of two subscribing witnesses.
